This invention relates generally to a device for dispensing various Ilubricating oils and isk particularly adapted for use with oil and gasoline filling stations. Y

It is. an object of this invention to construct a .novel device capable of dispensing anly one of a plurality of grades of lubricating o1 s.

Itis a further object of this inventionto devise a dispensing apparatus having a plurality of dispensing units for different grades of oil, and which has a construction which facilitates access to the various units.

It is a further object of this invention to devise anovelV dispensing unit utilizing a glass or transparent indicating vessel thru vhich the oil being dispensed is caused to It isa further object'of this invention to devise 'a dispensing unit in which the transparent indicating vessel is notsubjected to oilpressure `during times when the operating valve of the unit is in off position.

' It is a further object of this invention to 25. devise a dispensing unit incorporating means forl preventing accumulation of air within the upper portion of thetransparent indicating vessel.` Y Q l Further objects of the invention will appear from the following description in which I have setlforth the preferred embodiment of my invention. It is to be understood that the appended claims are to lbe accorded a range of equivalents consistent'with the state of the Figure 1 is a side elevational view partly in cross-section illustrating an apparatus ncorporating certain principles'of my invention.- f f Figure 2 is a cross sectional view taken along the line 2-2 of Fig. 1. n

` rlphe apparatus which I'have illustrated in 60 Fig. 1 incorporates in general a suitable supporting structure 10 upon which is mounted a vertical standard ll carrying a plurality of circumferentially spaced dispensing units 12. The supporting vstructure 10 has been 65 shown as cylindrical in shape altho it maybe of any suitable form such as square or Octagonal, and it preferably carries an outer slidable jacket 13 which Vcan be raised and latched upon a cover 14, to prevent access to the dispensing units. n

Standard 11 is preferably journaled to the ksupporting structure 10 as by means of a journal 16, so that the standard together with the dispensing units 12 can be rotated about 75' a vertical axis. This construction facilitates operation of the device since an operator standing in one position can dispense oil from anyone of the units 12 by rotating the standard 11. The vari-ous dispensing units Vare separately connected to different tanks so that they can be employed for dispensing different grades of oil. Forlthis purpose I prefer to employ pipes 17 communicating' with the different units 12 and extending 85 down into the interior vlof structure 10 thru the hollow standard 11. Pipes-18 which communicate with the various oil tanks are c0nnected to pipes 17 thru flexible pipe rsections 19. The use of flexible pipe sections is asim- Y ple means of permitting free rotation of standard 11 thru at least 360, altho it is to be understood that other yeXpedients can be employed. In order to collect oil which may be spilled or dripped from the dispensing units 12, I have shown a drip .pan`21 removably positioned within the upper portion 'of the supporting structure 10, and these pans` are preferably covered by a removable' tional screen 22. f

One novel form of dispensing unit which. I can incorporate in the apparatus of Fig. 1, is shown in Fig. 5. This unit consists of a body member 23 having an inlet opening 24 for connection with pipes 17 or some other source of -oil under pressure, and a discharge opening 26 thru which the oil is dispensed. Formed within the body member 23 `there is a tapered valve seat within Ywhich is fitted a tapered rotatable valve plug- 27. A manually operable lever 2S is secured to the outer end of plug 27 as by means of a cap screw 29, and the plug is normally resiliently urged against its seat by means of a compression spring 31. One end of spring 31 seats upon the inner face of lever 23 while the other end is shown seated upon a suitable vthrust washer 32, the washer being preferably `of fiber or like material.

Mounted upon the upper face of body member 23, there is a visual indicating vessel oli' transparent material such as glass. The upper end of this cylinder is closed by suitable metal cap34, and the assembly of the vessel 33 and cap .34 is clamped together and to the body `member 23 by means of a central pipe 36.

In order to cause llow of oil thru the vessel 33, body member 23 has an inflow opening 38 communicating with the lower portion of vessel 33, while the upper end of the vessel is in'communication with the interior of pipe 36 thru one or more openings 39. The lower portion of pipe 36, which is preferably threaded -into body member 23, communicates with an outflow opening 41.

In order to control flow of oil from the discharge `opening 26, the valve plug 27 is preferably provided with two ports '42 and 43. Port 42 serves to establish or interrupt communication between inlet opening 24 and the inflow opening 33 to the vessel 33, -while port 43-serves to interrupt or establish' communication between the outflow opening 41 and the discharge opening 26. The ositioning of these -ports is such that with the plug 27 in one position, as for example as that shown in Fig. 5, oil is free to iiow from the `inlet vopening 24 to the inflow 4opening 33 fthru port 42, and from vessel 33the oil can lilow thru opening 39, down thru the central lpipe -36 and out the discharge opening 26f-by way "of opening 41 and port 43. When lever28 :is moved `to closed position or the plug `27 "moved thru an angle of say 90o from that shown in Fig. v5, communication between the inlet opening `24 and 'vessel 33 is interrupted, and likewise communication between vessel 33 and the discharge 26 is interrupted. The fact that rotation of the plug 27 interrupts .communication between the inlet 24 and the glass vessel 33 isa distinct advantage, since when 'the valve is Vin closed position, the vessel is not subjected to the pressure of oil from the source to which the unit is connected. Thus if the vessel should become broken, the large quantities of oil would not be discharged as would be the case of inflow 24 and the glass vessel were in continuous communication. Furthermore, because of the absence of high pressure the glass vessel is less vapt to be broken. To prevent subjecting oil pressure to vessel33, While thevplug is being rotated from open to closed position port 42 cuts of vcommunication between -the vessel and inflow 38 before coinmunication is interrupted between the vessel and discharge 26.

It is .characteristic .of the dispensing unit shown in Fig. 5 "that Aan air pocket will not accumulate lin the upper end of the indicating vessel 33. If air "is introduced;I thru the inlet 24'with the oil it is immediately dis charged thru the opening 39.

In manyinstances I have found that it is desirable `to provide an Iannular yshoulder 44 about the discharge 'opening 26, the lower edge of this opening extending a substantial distance below the lower edge oit opening 26. This construction seems to aid in producing a solid and even stream of oil.

In Figs. 6, 7, and 8 I have shown a lmodified form of the apparatus as shown in Figs. 1, 2 `and 3. In this case, instead of employing tanks which are positioned at remote points from the dispensing apparatus, a plurality of tanks 45 are positioned rwithin the supporting structure 10. These tanks have findividual flexible pipe connections 46' with pipes 17 positioned within hollow standard 11. YIn `order to permit filling of-'these tanks there fis provided a series rof pipes 47 which extend into the upper portion of supporting structure 10 and which are provided with -re movable filling caps 'or Yplugs'48. Oil 'is preferably forced from the various 'oil tanks by air pressure .suppliedby series of air `pipes 51, these pipes connecting to a commonsource of lair v'thru pipe 52.

In Fig. l9 I have Ashown a modiliedfform of the dispensing unitof Fig. 5. In `this case the lower vend of central pipe 36 communicates with "the inflow opening 38, while the lower portion of'vessel 33 communicates with the outlet opening 41. In order to prevent accumulating of air within the upper end of vessel 33 I have provided a small tube or pipe 51 having its upper fopen end ycommunicating with the upper end of vessel 33 and lits lower end terminating -near or within the outflow opening 41. If 'air is introduced into vessel `33 'it Yis immediately removed thru pipe or tube 51,1when 'the valve is in open position. 'In this form I have also shown one or more smallopenings 52 communicant ing between ports 42 and43. These openings serve 'to `lay-.passa certain amount of oi'l directly from the `inlet opening24 .tothe discommunication between said inlet and inflow openings and communication between said outflow and discharge openings and in another position serving to interrupt communication between said inlet and inflow openings and communication between said outflow and discharge openings.

2. An oil dispensing device comprising a body member having oil inlet and discharge openings, a. transparent vessel mounted upon said body member and extending vertically from the same, said body having an iniow opening communicating with the lower .end of the vessel and an outflow passage extended from said body to the upper portion of said vessel, and valve means associated with said body for positively controlling flow of oil thru the inflow opening'and the outflow passage in the body and thru said vessel.

3. An oil dispensing device comprising a body member having an inlet opening for for connection to a source of oil under pressure, a transparent vessel mounted upon and supported by said body, said body having passages for establishing communication with said vessel, an open pipe extending into the vessel :from one of the passages, and a manually operable valve plug disposed in said body for controlling said communication.

6. An oil dispensing device comprising a supporting casing, a hollow standard mount- .ed upon said casing,a plurality of dispens ing units mounted on the standard for ro tation with respect to the casing, a plurality of oil tanks, and means extending through the hollow standard for establishing com-V munication between the dispensing units and the oil tanks.

In testimony whereof, I have hereunto set m hand. Y
